[PATCH 0/2] Port `git submodule init` from shell to C

This is a resend of origin/sb/submodule-init (and it still applies on 
top of submodule-parallel-update)

I squashed a change which Michael Haggerty proposed in one of the
large cleanup series preparing for the new refs backend. (18/21)
As that is the only fix in that series touching submodules,
picking it up here would untangle sb/submodule-init from that series.

Thanks,
Stefan
